NVIDIA video overlay

I'm using Nvid drivers i've gotten my screen perfect in both monitor and tv but when i use the video overlay the video is too big in the tv if i go into device adjustments and alter it looks perfect but as soon as i stop and restart a video it goes back to what it use to be. I even tried making the desktop view smaller but it did not affect the video overlay and i don't have a option to alter the device adjustments of the video overlay any ideas?
